多基阵联合的定位系统具有较强的抗干扰能力和生存能力,常用于水下目标定位。基于稀疏重构,提出一种适用于水声网络的分布式三基阵联合的纯方位定位算法。除了经典的线性阵列,引入球麦克风阵列,利用其三维特性提高定位精度,并将稀疏重构用于定位算法。仿真结果表明,三基阵联合的纯方位定位算法可以实现精准定位。

Multi-array combined positioning system has strong anti-jamming ability and survivability,and is often used for underwater target positioning.Based on sparse reconstruction,a bearing-only positioning algorithm for underwater acoustic network is proposed.In addition to the classical linear array,the spherical microphone array is introduced to improve the positioning accuracy by using its three-dimensional characteristics,and sparse reconstruction is used in the positioning algorithm.The simulation results show that the bearings-only positioning algorithm combined with three arrays can achieve accurate positioning.
